Revision 1.1 PRELIMINARY SanDisk iNAND Product Manual

1 Introduction

1.1 General Description

The SanDisk iNAND is a very small, flash storage device, designed specifically for storage

applications that put a premium on small form factor, low power and low cost. Flash is the

ideal storage medium for portable, battery-powered devices. It features low power

consumption and is non-vo latile, requiring no power to maintain the stored data. It also has

a wide operating range for temperature, shock and vibration. It is compatible with the JC64

FBGA 169, 0.5mm ball pitch, package.

SanDisk iNAND is well-suited to meet the needs of small, low power, electronic devices.

With form factors measuring 12mm x 16mm x 1.2 mm and 12mm x 18mm x 1.2mm,

iNAND is expected to be used in a wide variety of portable devices like mobile phones,

pagers, and voice recorders.

To support this wide range of applications, iNAND is offered with an SD Interface. The SD

interface product is f ully compatible with iNAND products, and provides a 4-b it da ta bus

for maximum performance. For compatibility with existing controllers, the iNAND offers,

in addition to these interfaces, an alternate communication -protocol based on the SPI

standard.

These interfaces allow for easy integration into any design, regardless of which type of

microprocessor is used. All device and interface configuration data (such as maximum

frequency and card identification) are stored on the device.

The SanDisk iNAND provides up to 8 GB of memory for use in mass storage applications.

In addition to the mass-storage-specific flash memory chip, iNAND includes an intelligent

controller, which manages interface protocols, data storage and retrieval, error correction

code (ECC) algorithms, defect handling and diagnostics, power management, wear

leveling, and clock control. Figure 1-1 is a block diagram of the SanDisk iNAND with SD

Interface.

Chapter 1 – Introduction

Revision 1.1 PRELIMINARY SanDisk iNAND Product Manual

1.5 Functional Description

The SanDisk iNAND contains a high-level, intelligent subsystem as shown in Figure 1-1.

This intelligent (microprocessor) subsystem provides many capabilities not found in other

types of memory cards. These capabilities includ e:

• Host independence from details of erasing and programming flash memory

• Sophisticated system for managing defects (analogous to systems found in magnetic

disk drives)

• Sophisticated system for error recovery including a powerful ECC

• Power management for low power operation

1.6 Technology Independence

The 512-byte sector size of the SanDisk iNAND is the same as that in an IDE magnetic

disk drive. To write or read a sector (or multiple sectors), the host software simply issues a

read or write command to the card. The command contains the address and number of

sectors to write or read. The host software then waits for the command to complete.

The host software does not get invo lved in the details of how the flash memory is erased,

programmed or read. This is extremely important because flash devices are expected to get

increasingly complex in the future. Because iNAND use an intelligent on-board controller,

host system software will not need to be updated as new flash memory evolves. In other

words, systems that support iNAND technology today will be able to access future SanDisk

devices built with n ew flash technology without having to update or change host software.

1.7 Defect and Error Management

The SanDisk iNAND contains a sophisticated defect and error management system. This

system is analogous to the systems found in magnetic disk drives and in many cases offers

enhancements. If necessary, iNAND will rewrite data from a defective sector to a good

sector. This is completely transparent to the host and does not consume any user data space.

The soft error rate specification for iNAND is much better than the magnetic disk drive

specification. In the extremely rare case that a read error does o ccur, iNAND has

innovative algorithms to recover the data. These defect and error management systems,

coupled with the solid state construction, give SanDisk iNAND unparalleled reliability.

1.8 Wear Leveling

Wear-leveling is an intrinsic part of the erase pooling functionality of iNAND.

1.9 Automatic Sleep Mode

A unique feature of iNAND is automatic entrance and exit from sleep mode. Upon

completion of an operation, cards enter sleep mode to conserve power if no further

commands are received in less than 5 milliseconds (ms). The host does not have to take any

action for this to occur. However, in order to achieve the lowest sleep current, the host

needs to shut down its clock to the card. In most systems, cards are in sleep mode except

when accessed by the host, thus conserving power.

Chapter 1 – Introduction

Revision 1.1 PRELIMINARY SanDisk iNAND Product Manual

When the host is ready to access a card in sleep mode, any command issued to it will cause

it to exit sleep, and respond.

1.10 iNAND — SD Bus Mode

The following sections provide valuable information on SanDisk iNAND in SD Bus mode.

SanDisk iNAND devices are fully compliant with the SDA Physical Layer Specification,

Version 2.00. Card Specific Data (CSD) Register structures are compliant with CSD

Structure 1.0 and 2.0.

This section covers Negotiating Operating Conditions, Card Acquisition and Identification,

Card Status, Memory Array Partitioning, Read/Write Operations, Data Transfer Rate, Data

Protection in Flash Cards, Write Protection, Copy Bit, and CSD Register.

Additional p ra c t i cal card detect i on m e t hods can be fo u nd in appl i cat i o n n ot es pert ai ning to

the SDA Physical Layer Specification, Version 2.00.

Figure 1- 3 Data Transfer Formats

Table 1-1 Mode Definitions

Mode Description

Single Block In this mode the host reads or writes one data block in a pre-specified length. The

data block transmission is protected with 16-bit CRC that is generated by the

sending unit and checked by the receiving unit.

The block length for read operations is limited by the device sector size (512 bytes)

but can be as small as a single byte. Misalignment is not allowed. Every data block

must be contained in a single physical sector.

The block length for write operations must be identical to the sector size and the

start address aligned to a sector boundary.

Multiple Block This mode is similar to the single block mode, except for the host can read/write

multiple data blocks (all have the same length) that are stored or retrieved from

contiguous memory addresses starting at the address specified in the command.

The operation is terminated with a stop transmission command.

Misalignment and block length restrictions apply to multiple blocks and are identical

to the single block read/write operations.

1.11 SPI Mode

The SPI Mode is a secondary communication protocol for iNAND devices. This mode is a

subset of the SD Protocol, designed to communicate with an SPI channel, commonly found

in Motorola and other vendors’ microcontrollers. Table 1-1 contains names and

descriptions of SPI Mode functions. More information about SPI Mode can be found in

Section 7 or the SDA Physical Layer Specifica tion, Version 2.00.

Chapter 4 – iNAND Protocol Description

Revision 1.1 PRELIMINARY SanDisk iNAND Product Manual

4 iNAND Protocol Description

4.1 General Description

iNAND protocol information is contained in this chapter; information includes bus

protocol, card identification, and a functional description.

4.2 SD Bus Protocol

Communication over the SD bus is based on command and data-bit streams initiated by a

start bit and terminated by a stop bit. See Section 3.6.1 of the SDA Physical Layer

Specification, Version 2.00 for details.

4.3 Functional Description

The host controls all communication between itself and iNAND. To demonstrate how this

communication works, this section provides a general overview of the card identification

and data transfer modes; commands; card dependencies; various card operation modes and

restrictions for controlling the clock signal. All iNAND commands, together with

corresponding responses, state transitions, error conditions, and timings are also provided.

For detailed information, refer to Section 4 of the SDA Physical Layer Specification,

Version 2.00.

4.3.1 Card Identification Mode

In Card Identification Mode the host resets all cards, validates operation voltage range,

identifies and requests cards to publish a relative card address. For more information see

Section 4.2 in the SDA Physical Layer Specification, Version 2.00.

4.3.2 Data Transfer Mode

In Data Transfer Mode, the host may operate iNAND in the fPP frequency range. This

section contains information about data read and write, erase, write protect management,

card lock/unlock operations, application-specific commands, the switch function command,

high-speed mode, the command system, the Send Interface Condition command (CMD8).

CMD8 is part of identification mode and command functional differences in high capacity

iNAND. For more detailed information, refer to Section 4.3 of the SDA Physical Layer

Specification, Version 2.00.

4.3.3 Clock Control

The host can use the bus clock signal in iNAND to switch them to energy saving mode or

to control data flow on the bus. See Section 4.4 of the SDA Physica l Layer Specification,

Version 2.00.

Chapter 4 – iNAND Protocol Description

Revision 1.1 PRELIMINARY SanDisk iNAND Product Manual

4.3.4 Cyclic Redundancy Codes

The Cyclic Redundancy Check (CRC) protects against transmission errors that may occur

on the iNAND bus. Detailed info rmation and examples for CRC7 an d CRC16 are provided

in Section 4.5 of the SDA Physical Layer Specification, Version 2.00.

4.3.5 Error Conditions

See Section 4.6 of the SD A Physical Layer Specification, Version 2.00.

4.3.6 Commands

See Section 4.7 of the SDA Physical Layer Specification, Version 2.00 for detailed

information about iNAND commands.

4.3.7 Card State Transition

The state transition is dependent on the received command. The transition is defined in

Section 4.8 of the SDA Physical Layer Specification, Version 2.00 along with responses

sent on the command line.

4.3.8 Timing Diagrams and Values

See Section 4.12 of the SDA Physical Layer Specification, Version 2.00.

4.3.9 Speed Clas s Specification

The speed class specification classifies card performance by speed class number and offers

the method to calculate performance. For more information, refer to Section 4.13 of the

SDA Physical Layer Specification, Version 2.00.

Appendix A –Power Delivery/Capacitor Specifications

Revision 1.1 PRELIMINARY SanDisk iNAND Product Manual

Appendix A Power Delivery and Capacitor Specifications

A.1 SanDisk iNAND Power Domains

SanDisk iNAND has three power domains assigned to VDD_H, VDD_F, and FCAP as

shown in Table 1.

Table 1. Power Domains

Pin Power Domain Comments

Supported voltage ranges:

High Voltage Region: 3.3V (nominal)

VDD_H Host Interface

Low Voltage Region: 1.8V (nominal)

Supported voltage range: VDD_F Memory

High Voltage Region: 3.3V (nominal)

FCAP Internal FCAP is the internal regulator connection to an

external decoupling capacitor.

A.2 Capacitor Connection Guidelines

A.2.1 FCAP Connections

The FCAP (C2) ball must only be connected to an external capacitor that is connected to

VSS. This signal may not be left floating. The capacitor ’s specifications and its placement

instructions are detailed below.

The capacitor is part of an internal voltage regulator that provides power to the controller.

Caution: Failure to follow the guidelines below or connecting the FCAP ball to any

external signal or power supply may cause the device to malfunction.

The trace requirements from the FCAP (C2) ball to the capacitor are as follows:

• Resistance: <2 ohm

• Inductance: <5 nH

The capacitor requirements are as follows:

• Capacitance: >=2.2 uF

• Voltage Rating: >=6.3 V

• Dielectric: X7R or X5R

Appendix A –Power Delivery/Capacitor Specifications

Revision 1.1 PRELIMINARY SanDisk iNAND Product Manual

A.2.2 VDD_H and VDD_F Connections

The iNAND has two power domains labeled: VDD_H and VDD_F. Currently both power

domains can be connected to the same 3.3V (nom) power supply. However, in order to

provide maximum flexibility and support low power operation in future iNAND devices,

the PCB should be desig ne d as foll ows:

• All VDD_F balls should be connected to a 3.3V supply

• All VDD_H balls should have the option of being connected either to a 3.3V or 1.8V

supply

SanDisk recommends providing separate bypass capacitors for each power domain as

shown in Figure 1.

Note: Signal routing in the diagram is for illustration purposes only and the final routing

depends on your PCB layout. Also, for clarity, the diagram does not show the VSS

connection. All balls marked VSS should be connected to a ground (GND) plane.
